The issue of heating a summer house or apartment building if the building is far from gas pipelines can be a real problem, since electricity is expensive today. A very good way out of this situation is the purchase of a solid fuel boiler or furnace. Such equipment is inexpensive, it is economical in operation. Particularly popular with owners of remote suburban areas are furnaces for homes with long burning.
Principle of operation
Such equipment functions a little differently than ordinary solid fuel "potbelly stoves" and "Dutch women". Firewood in the furnace of such stoves does not burn, but smolder, which provides a long and quite sufficient heating of the air in the room. Smoke in constructions of this type enters the afterburner, where it finally burns. This greatly increases the efficiency of the furnace. Thus, using this equipment can significantly save on fuel. Bookmark the latter is usually done no more than twice a day.
Long-burning heating furnaces usually operate by air-convection method. It also allows you to increase productivity. Cold air from the floor of the room enters the nozzles or openings in the furnace body. Heating occurs when moving it between the casing and the walls of the furnace. Hot air comes out of the pipes or openings from above, heating the room.
Long-burning heating stoves work on wood, sawdust, wood chips, coal, peat and even household waste. Their smoke is not as caustic as in conventional models.
Main advantages
In addition to efficiency, this type of furnace has the following advantages:
- Compact size.
- Cheap.
- Easy to install.
- Easy to maintain and operate.
- Multifunctionality. You can use stoves for a long-burning house not only for heating premises, but also for cooking. Since many manufacturers carefully consider the design of such equipment, in some cases it can even become a stylish decoration of the interior.
Water circuit models
Stoves for a long burning wood burning house work quite efficiently even without connecting pipes and radiators. However, for larger rooms, additional use of highways may be the best option. In the simplest models with a water circuit, a sealed cylinder with two nozzles is installed on the chimney, to which the supply and return pipes of the heating system are connected. The circulation pump is pumping the coolant. To control the pressure of the coolant, an expansion tank is used. Heating radiators can be used by anyone.
Very often, stoves for a long-burning house with a water circuit are installed as an alternative heating device in addition to a gas or solid fuel boiler.
Long burning furnace: do it yourself
Next, we consider how to make the simplest design of this type from improvised materials. In the people, such a furnace is called a "bubafone." It consists of the following nodes:
- combustion chamber
- blowing piston
- covers
- chimney.
Production of a combustion chamber
This is the most dimensional and important element of the furnace. You can make it from a regular iron round or rectangular barrel of 200 liters. From this container, you need to remove the cover and cut a hole in it under the piston-blower pipe. The barrel should be closed with a lid as tightly as possible. The more tight the stove, the longer the wood will burn in it.
Blew piston
Ovens for a long burning wood burning house work with a minimum amount of oxygen. The latter is fed to the “bubafon” through a blower, located not from below, as in conventional models, but from above. To make a piston, you need a pipe with a diameter of 100 mm. You will also need a steel disk slightly smaller than the barrel itself, of a diameter with a hole of 100 mm in the center. Four corners with wide shelves are welded on it crosswise from the middle to the edges. In this way, channels are arranged through which air will be distributed throughout the entire volume of the furnace. Next, the disk with “blades” is welded to the bottom of the pipe. The result is a large piston with a special design. It must be inserted into the hole in the barrel lid. A valve is installed on top of the blower pipe to regulate traction.
Combustion products
Long-burning heating stoves smoke quite intensively. Therefore, the use of a device for venting gases in them is necessary. The chimney is welded to the side at the top of the barrel through the pipe. It is led out into the street either through a hole in the wall, or through a ceiling and roof.
Wood burning stoves: reviews
Opinions of the Russian owners of suburban areas about these stoves have developed quite controversial. Some of this equipment is just thrilled. Others complain about the need for very frequent cleaning of the chimney. A similar problem may indeed occur. But only in case of improper installation and use of the furnace. When installing the stove, special attention should be paid to the assembly of the chimney. It must be carried out exactly according to the instructions. Clogging or even burning a furnace of this design will only occur when using the wrong fuel. Which can be used is indicated by the manufacturer.
Of the positive qualities, consumers note first of all, of course, the effectiveness and efficiency of this equipment. However, it is recommended to use it only for heating small houses or as an alternative source of heat. In large houses, it is still recommended to install the usual high-grade heating equipment.
Industrial Model Installation
Installation of such finished equipment as stoves for a long burning wood burning house is an even simpler procedure than assembling a structure from scratch. The only difficulty is that you have to place such models almost close to the wall, since the outlet pipe for the chimney is located behind them. In a wooden house, this can be dangerous. Therefore, the wall must first be laid with heat-resistant materials. The legs of industrial models are usually adjustable, which further facilitates installation.
The cover of finished stoves is most often deaf metal. However, for an additional fee, the manufacturer provides the consumer with the opportunity to purchase a transparent door made of thick heat-resistant glass. A similar element enhances the aesthetic qualities of the structure. Among other things, nowadays beautiful long-burning stoves-fireplaces are produced.
Popular brands
Next, let's see what models of stoves of this type are popular in the modern heating equipment market. A very good solution would be, for example, buying a Lavoro brand design. These models are produced by a domestic company supplying a wide variety of furnace equipment to the market. These are very economical units, compact and able to work on one tab up to 8 hours. Another advantage is one hundred percent maintainability. To get access to absolutely any node if necessary is not difficult. The efficiency of these furnaces is about 85%.
Quite popular with owners of country houses and garages are models of the Ermak brand. Due to the built-in convection pipes, these stoves provide very quick heating of the room. Their efficiency is approximately 80%.
Prices
There are stoves of long burning, as already mentioned very inexpensive. The price of them depends primarily on performance, brand and design complexity. In online stores you can buy both pretty simple small models for 7-10 thousand rubles, and large complex designs with a very high efficiency for 20 000 rubles.
As you can see, stoves for a long-burning house - the equipment is very convenient and inexpensive. Of course, it is better to use a full-fledged boiler to heat a large cottage. However, for heating a small country house in autumn or spring, the best option for equipment can not be found.
